Gory Blister

With a name like Gory Blister, you know you're going to get death metal
of some sort, though in the case of this Italian mob, it's of the
technical nature, with a hyperactive, high-precision style full of twists
and turns.
The band formed back in 1990 and recorded the requisite demos before
finally getting to a proper release in 1996, and they've averaged a new
release every few years since.
